A Novel Entry into Cyclopropanated Sugar Amino Acids

Reaction of sugar triflates (1) and (2) with tert-butyl cyanoacetate in presence of sodium hydride affords the cyclopropanated sugars (3) and (4), followed by selective hydrolysis of the ester group to free acids (5) and (6), respectively.Couplings of (5)

Synthesis of Disubstituted Cyclopropapyranosides from 2,3-Epoxy-4-triflate-pyranosides

Reaction of benzyl 2,3-anhydro-4-O-trifluoromethylsulfonyl-β-L-ribopyranoside (1) and benzyl 2,3-anhydro-4-O-trifluoromethylsulfonyl-α-D-ribopyranoside (4) with malonic acid derivatives yields, via the carbanions, the cyclopropa-monosaccharides 3 and 6.The ester residues attached to the cyclopropane moiety can be saponified to give the corresponding acids which can be coupled to new carbohydrate amino acid derivatives of type 9 which are of biological interest in different immunological assays.
